Problems solved by technology

[0010] At present, the hydrogen evolution reaction problem of lead-carbon batteries needs to be further solved, and the electrode materials have certain environmental pollution.
Carbon nitride has the characteristics of low density, stable chemical properties, no harm to the human body, and environmental protection. It can be tried as a carbon source in electrode materials. However, there is no research on g-C 3 N 4 As a carbon source for lead-carbon batteries, the hydrogen evolution reaction problem of lead-carbon batteries has not been solved

Description

technical field [0001] The invention relates to the technical field of battery energy storage, in particular to a g-C 3 N 4 The negative electrode material and negative electrode of lead-carbon battery with hydrogen evolution inhibitor as carbon source. Background technique [0002] A lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main component of the positive and negative electrodes is lead sulfate. [0003] The cycle use of lead-acid batteries under high-rate partial state of charge (HRPSoC) will cause irreversible sulfation of the negative electrode, which greatly reduces the service life of lead-acid batteries, which greatly affects the application of lead-acid batteries in many fi...
